Bigby's Fantastic Fencers

This spell creates one hand for every three levels of the caster, each of which holds a longsword.  Each hand fights with the skill of a fighter of one-half the experience level of the caster.  Each hand is AC 12 because of its size and speed, and each can sustain 22pts of damage before being dispelled.  Each fencer is capable of disarming an opponent and does so on a roll of four greater than what is needed to hit.  The caster need not concentrate on the fencers to keep them functioning, but only has to give them orders as if they were henchmen.
